what do you mean by PF correction. A motor is rated at 15
kw,415 volts, 0.7 pf and eff of 0.92. The powerfactor is
improved to 0.98 by adding capacitors at the bus. calculate
the current drawn by motor under full load condition before
and after pf correction

Answer Posted / technicalarticlessbsvbsbsvb

No change. whatever was at rated pf will continue to be
drawn

Is This Answer Correct ?    2 Yes 5 No
